Hair styling appliance comprising a removable reservoir

ABSTRACT

A hair styling appliance includes a base including a mount and a removable reservoir configured to take up a disconnected position in which the reservoir is away from the mount and an operating position in which the reservoir engages fluidically with the mount, a portable unit remote from the base; a line that fluidically connects the base and the portable unit; wherein the base also includes a detection system having a detector configured to detect the passage of the reservoir from the disconnected position to the operating position.

This invention concerns a hair styling appliance using steam and intended to shape hair by contact, intended in particular for straightening, curling or crimping the hair of a user.

Two traditionally known types of hair styling appliances for straightening, curling or crimping have hair clamping surfaces that are flat, curved or uneven, and are heated or heating.

Hair styling appliances like straightening, curling or crimping irons generally comprise a portable unit with two pivoting jaws. The jaws each comprise an extremity supporting a treatment surface, at least one of the treatment surfaces being heated, the other being provided to bring the hair into contact with the first surface, in particular by moving from an open position of the jaws, allowing the hair to be inserted, to a closed position for putting the hair into contact with the heating part.

The other extremity of the jaws forms two handle halves acting as a gripping area and making it possible to move from the open position to the closed position. The movement is performed manually by pressing the two articulated handle halves of the appliance towards one another to bring the treatment surfaces into contact with the hair. A strand of hair is straightened by moving the appliance along this strand, from the root to the end. A strand of hair is curled by winding the strand at least partially around the treatment surface(s) and applying heat to set the curl primarily statically.

In such appliances, it is envisioned to also use steam sprayed onto the hair in order to improve the shaping of the hair.

To improve the steaming capacity of the hair styling appliance, it is known, in particular from the document EP2449912, to separate the storage means for the fluid used to produce the steam. The hair styling appliance thus comprises a base with a removable reservoir intended to store the fluid. After filling the reservoir, the user attaches it to a mount of the base in order to allow a fluid connection between the mount and the reservoir. The mount of the base comprises a suction/discharge device for carrying the fluid towards fluid steaming means arranged in the portable unit of the hair styling appliance.

However, the fluid connection between the reservoir and the mount is sometimes poorly executed. In fact, the user may fail to position the reservoir correctly so that it is in sealed fluid communication with the mount. The steaming capacity of the hair styling appliance is then not optimal, and the efficacy of the appliance is affected by this. In addition, a poor fluid connection or a non-sealed fluid connection could damage the appliance and cause malfunctions.

The goal of this invention is to remedy all or a portion of the aforementioned drawbacks. To this end, this invention concerns a base of a hair styling apparatus comprising:
